Is it me?

Hi everyone,

Over the course of the last few months, I've lost a lot of friends and I'm starting to believe it's my fault and that I need to change. A friend of mine accused me of trash talking her to my manager and etc when I never did. I reached out to her and she ignored my message responding with "I am unhappy with you". When I asked her why and what I could do fix it and etc, she ignored my message. She's been going out with coworkers and common friends on social media and I am very hurt. This has happened so many times with other people I don't really know what to do with myself.

My appetite has been all over the place, I'm exhausted and I feel so upset all the time.
